I dunno if they will, but I would like to see the Kor'kron kicked out of Undercity. I remember when they replaced all our Abomination guards. Blasphemy!

yeah even though my hordie didnt use undercity often it just felt so wrong to see a bunch of orcs instead of happy derp face aboms.

sure the aboms are made from a mish mash of different men women and children but all they wanna does is pick flowers Y U NO LET ABOMS PICK FLOWERS @_@

You're assuming that she wants to jump the band wagon. Let's say she does and Voljin loses? (we know he won't, but the NPCs don't).

For now, the war is far from her door step and she doesn't have any real ties to the Horde. As such, I expect her to sit back and watch, waiting for the opportune moment to strike at the turn of the tide. If Garrosh is obviously about to lose, she'll join in and share in the glory of ousting a tyrant.

If Garrosh is about to win, she'll swoop in and kill the rebels, proving her "loyalty" to the warchief and possibly earning some relaxation on the Kokron presence in Undercity.

Unless they completely forget for some reason then they'll definitely be withdrawn or killed in the Undercity. They are Kor'kron afterall, and the Forsaken and Sylvanas have zero respect for any of them. As soon as Sylvanas gets word that the rebellion is going to happen, all of those Kor'kron are goners.
